The first time I shot my Omega I used the T7 pellets. Very convient but they do absorb moisture. By the time I got to the end of the pellets, I did notice that they were.....not bone dry, just a whisker damp (for lack of a better word). My Omega loved them, they were very convienient but it was the absorbing affect that turned me off. The crumbled when I seated my sabot, I could fell them compress. There was no solid stop like there was before. Just my experience.
